A Study on the Auto-generation of MBSE Models from Design Documents

Abstract

In recent years MBSE (Model Based Systems Engineering) has gained popularity as a useful methodology for overviewing the whole structure, functionality and requirements of products and identifying the impact range of design changes. However, construction of system models for MBSE is time-consuming, which prohibits the usage of MBSE in actual product design scenes. Our goal is to reduce human effort in constructing MBSE models by automatically generating SysML (Systems Modelling Language) diagrams from design documents. In this study, as an advancement of the automatic generation technology for the requirement model and component structure model, we create a functional model from the functional definition document and develop the automatic generation technology for the MBSE composite model that links the functional model, requirement model, and component structure model. The following summarizes the key points of the obtained results. We have constructed a prototype that automatically generates the MBSE composite model by creating a functional model from the functional definition document and linking it with the requirement model and component structure model. We have developed a function to automatically generate sub-models composed of specific related data of requirements, functions, and component structures in response to the designer's query..
